The video shows a sea otter trading a pebble in exchange for a fish, demonstrating its intelligent nature and use of tools to smash open crustaceans such as sea snails. The intelligent sea otters use small rocks and pebbles as tools and store them in a pouch under their arm so they can use them whenever they need to. They also keep these rocks for several dives. Sea otters are considered among the most intelligent creatures in our oceans, alongside dolphins and octopuses, and are known for their intelligence and use tools like a hammer. The trade requires learning and an appreciation of the value of these pebbys. The video was featured on A-Z Animals.
